My Pump is really noisy so I am going to do something about it soon. Just came across this tip in an American Forum. Bubblewrap.. Now Ive got loads of that! The text below in red is not mine, it accompanied the photo


Had seen on other threads the idea of using a sound insulating material when re-mounting the pump, but I had some clearance issues to deal with. The pump is located on the floor under the drawer beneath the oven. Easy to get to, but had to watch the clearance on the drawer. So, I fastened the pump to a piece of that Pergo fake wood flooring stuff, leftover from when we put Pergo fake wood flooring in our house. Then, I sandwiched a folded piece of bubble-wrap between that and the floor and fastened it down with screws.

Although you can still hear it, I would say it's probably 25 percent of the noise it was before. Awesome! Thanks to all for the tips!

Jim,

I had a noisy Shurflo pump and it turned out that the two bolts that hold the pump in its housing had worked loose. I tightened them and all was well.::bigsmile:

Just a thought.::bigsmile:

Hi Jim
If your pump is connected directly to solid plastic pipe (most RVs are) it will always be noisy, Linda sells a kit which comprises two pieces of flexible hose with connectors, this reduces the noise conducted along the pipes.

Why they fit the pumps inside the RV beats me, they would be much less noise if fitted in the belly locker near the tank..

hi jim.
if your pump mounts as in the photo you could go to your local model shop and ask for a set of engine mounting rubber bobbins for model aircraft and fix the pump to these.
I used them on a 6ft wingspan aircraft with a 23cc single cylinder petrol engine and the vibs went from jackhammer to zero and the resonated noise stopped as well.
it wont stop the diaphram noise but they will stop vibration and resonance thru the bodywork.
they are a miniture version of BL MINI exhaust mount rubber bobbins.
see them here.
